Business Unit: EPS Mobility
Role: Design for Manufacturing Engineer - Motor
The Design for Manufacturing Engineer will be responsible for DFM activities for EV Traction Motors and sub-assemblies and translating product requirements and design intent into production ready designs, tooling specs, and robust, capable processes. You will run DFM/DFA reviews, lead PFMEA/Control Plan creation, drive supplier APQP/PPAP, and ensure factory readiness for yield, throughput, safety, and cost.
Key Responsibilities
DFM/DFA & Industrialization
- Perform DFM/DFA on stator and rotor assemblies: laminations, stacking, interlocks; hairpin and conventional winding; forming, welding/brazing, impregnation/varnish, encapsulation, balancing, and mechanical assembly.
- Optimize tolerances & GD&T for manufacturability and process capability; define datum strategy, stackup, and critical to quality (CTQ) features.
- Convert design intent into tooling/fixture and automation requirements (winding, insertion, forming, laser welds, machining, sealant dispensing, EOL testing).
- Lead process validation (IQ/OQ/PQ) and capability studies (Cp/Cpk) for key dimensions and electrical parameters.
CrossFunctional Interface
- Partner with Design Engineering to influence materials, geometry, and joining methods for manufacturability, NVH, thermal performance, and reliability.
- Work with Operations/ME on line layout, takt time, ergonomics, PokaYoke, standard work, and OEE improvement.
- Collaborate with Supply Chain/SQE on makebuy, shouldcost, supplier DFM workshops, APQP deliverables, PPAP, and incoming quality plans.
- Support EOL test strategy definition (electrical performance, partial discharge, vibration, noise, insulation resistance).
Quality, Safety & Compliance
- Create and maintain PFMEA, Control Plans, Work Instructions, MSA plans (gage R&R), and SPC charts for highrisk features.
- Ensure compliance with IATF 16949/ISO 9001, relevant IEC 60034 test methods, RoHS/REACH, and functional safety interfaces (with system safety/ISO 26262 teams as applicable).
- Drive root cause analysis (5Why, Fishbone, 8D) for yield, scrap, and warranty issues; implement robust corrective and preventive actions.
- Champion EHS in processes (resins, solvents, lasers, highvoltage handling) and machine safety interlocks.
Cost, Yield & Throughput
- Conduct VAVE and designtocost activities (copper fill factor, lamination utilization, process simplification, material substitutions).
- Reduce cycle time and changeover through SMED, errorproofing, and automation refinement; track FPY, scrap, and rework trends.
- Build control dashboards for capability (Cp/Cpk), FPY, PPM, and PPAP status.
Qualifications
- Bachelor's or Master's degree in Electrical, Electronics or Computer Science Engineering.
- 2-10 years of experience in electric motor design/manufacturing, with at least 5 years in a senior leadership position within a Tier-1 supplier/OEM.
- Hands-on experience with motor manufacturing processes: lamination stamping/stacking, hairpin/conventional winding, insulation systems, laser welding etc.
- Familiarity with IATF 16949/ISO 9001 systems and production part approval
- Proficiency with CAD (NX/CATIA/Solidworks) and data tools (Excel/Minitab/Power BI) for capability and DOE analysis
- Excellent communication, stakeholder management and decision making under ambiguity
